The stock Original Xbox fan is a 70mm sleeve-bearing unit that has had twenty years to get noisy, and swapping it for a Noctua is one of the cheapest quality-of-life upgrades you can make. The problem is that the NF-A6x25 is a 60mm fan and the Xbox mount is not. This 3D printed adapter bridges that gap: it holds the Noctua at the correct position over the heatsinks and screws into the existing mounting points.
No cutting, no drilling, nothing permanent. Design credit to @mafredri_55747 via Printables.

- 1x 3D printed fan adapter

Installation
Difficulty: Moderate. Tools: Torx driver for the housing, Phillips for the fan mount. No soldering unless your fan header needs rewiring. Time: 20-30 minutes.
Open the console, remove the stock fan and shroud, fit the Noctua into the adapter, and mount the assembly onto the existing points.
